Hardware, Embedded Systems Few hardware vendors have not yet launched their own mini laptop (or, "netbook"). Most brands these days produce their own version of the same hardware, with Intel's i386-compatible Atom cpu's and Windows XP installed on a spinning hard drive or sometimes still a solid state disk. Some Linux models are still sold by some vendors, among whom Asus, which more or less started selling in this OLPC-inspired genre of laptops.

64-bit netbook

I believe Loongson based netbooks are the only 64-bit netbooks in the world, Intel's Atom only offers x64 mode for the desktop models (Atom 230 and 330).

True, but off hand I can't think of any particular reason 64-bit would make a difference in the current generations of Atom netbooks. The RAM is maxed at 2gb, so you don't need the extra availability of RAM that 64-bit offers and, given that 64-bit apps can take more memory than their 32-bit equivalents, it would seem that remaining 32-bit would be optimal for the current Atom netbooks. I'm not sure the extra RAM used would justify the rather small speed increases given the tasks that the Atom netbooks are designed for (web browsing, office tasks, etc). It's not like they're video editing powerhouses.

Not knowing a lot about MIPS, however, the same rules may not apply as with x86_64, and the impact might be much more dramatic on that platform.

I develop server applications, and having access to a 64-bit netbook would be nice!!

There are always bugs that assume integers and pointers are of the same size, and it is almost impossible to test for these kinds of bugs on a 32-bit platform. :-)
